IMPROVEMENT IN TRUSSED AXLES FOR WAGONS.

Specification forming part of Letters Patent No. 212,378, dated February 18, 1879 5 application filed December 23, 1878.

To all whom t may concern:

Be it known that I, JOHN HERBY, of Jamestown, in the county of Chautauqua and State of N ew York, have invented certain new and useful Improvements in a Truss for Wagon- Axles 5 and I do hereby declare that the following is a full, clear, and exact description of the that class ot' wagons having pipe-skeins with a suitable metal clamp having holes through it to receive clips, that pass over the skein and arefastened by nuts and made to extend below the axle to receive the ends of rods that extend from skein to skein, and are held in position byA a bridge or bridges, as will be readily u'nderstood by the drawing, in which the ligure shows an axle with my invention attached thereto.

In farm-wagons and oth ers used to transport heavy loads it has always been found difficult to make axles that would sustain the continued strain brought on them, and they are most liable to break close to the skein; and to overcome this difficulty various methods have been employed, some ot' which have been somewhat beneficial. This expense and trouble are cntirely overcome by my invention.

In the drawing, A represents a com mon axlewood. B is a cast pipe-skein, made in the usual form. E is a skein-clamp, made of suitable metal, and formed to fit the under side of the pipe-skein, having a vertical ledge on one edge, that drops far enough below the axle to receive the rods F F, which passV through it, and also lips d, having holes through which the clips D pass, after extending over the pipe-skein, and are secured by nuts.

The rods F F are made to extend from the pipe-skein on one end of the axle to that on the other end. They pass through the ledge ofthe skein-clamp, and are secured by the nuts j f.

The bridges G Gr are properly fastened to the axle a short distance from the skeins, and are made to extend far enough below the end of the rods passing through the clamp to cause the rods F F to stand bracing cach way, said rods being held firmly in place by turning up the nuts fj'.

One bridge in the center of the axle would do; but I prefer to use two, as shown, as they stay the rods in place, and keep them from springing when the wheels strike any obstruction.

Pipe-skeins are commonly held on the axle by a screw-bolt passing into the end of the axle 5 but this cut-s away the timber, and is not as secure as when held by the rods, as in the manner shown.

The clamp and clip being drawn tightly around the pipe-skein greatly strengthens it; and as the skein is larger at the base than at any other part, there is no trouble in clamping them tight enough to hold securely in place, and to make them more secure the clamp may rest against the bead O of the pipe-skein, as shown.

The device may be readily applied to any pipe-skein wagon already built or to be built, as will be readily understood.

I am aware that a single rod extendin g the length of the axle, and fastened to the pipeskeins in various forms, has been employed; but this only partially overcomes the liability' to break, as any heavy side strain is liable to break the axle before there is much strain on the rod.

As my device provides for both vertical and lateral strain, there is no trouble in making the axle strong enough to carry as heavy a load as any other part of the wagon.

I claim- In combination with wagon-axles, the skeincla-mp E, clip D, truss-rods F F, and bridges G G, used in the manner and for the purpose set forth.

In testimony' that I claim the foregoing" as my own invention I aftix my signature in presence of two witnesses.
